Animating UILabel textcolor is not easy as it seems, normal animation won't work on this property. The below code snippet animates the UILabel textcolor as in button click.
Change the duration and UIViewAnimationOptions to play with it.
extension UILabel{
func flashLabel() {
func animate(duration:Double,alpha:CGFloat,completion:(()->())?){
UIView.transition(with: self, duration: duration, options: UIViewAnimationOptions.transitionCrossDissolve, animations: {
self.textColor = self.textColor?.withAlphaComponent(alpha)
}) { _ in
completion?()
}
}
animate(duration: 0.1, alpha: 0) {
animate(duration: 0.3, alpha: 1, completion: nil)
}
}
}
Happy coding...
